SECTIONAL HEATER.

SPECIFICATION forming part of Letters Patent N0. 676,688, dated June 18, 1901.

Applicationfiled March 19, 1900. Serial No. 9,301i (No model.)

T all whom, it may concern:

Be it known that I, SAMUEL E. PORTER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Sectional Heaters, of which the following is a specification, reference being had to the accompanying draw ings, forming a part thereof.

The main object of my invention is to produce a sectional water-heater that shall be simple in construction, efficient and economical in operation, easily assembled and set up, and that shall occupy a small door-space.

It consists in a novel construction and arrangement of parts, as hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in both figures.

Figure 1 is a vertical medial section of a heater embodying myinvention and Fig. 2 is a perspective view of the same, the sections being separated above the re-pot and parts being broken away and shown in section.

The heater is of a generally cylindrical form and composed of approximately circular sections arranged one above another.

A is the ash-pit, which is preferably made of semicylindrical form at the back and square or straight in front, Where the ash-pit opening and door are located.

Bis the fire-pot section, which is formed with' an annular water space or passage b, extending clear around the fire pot. In the back and near the bottom of said section is an inlet-opening h', with which the feed-water supply or return pipe O is connected, and in the top at the front and to one side of the center is an outlet-opening h2. The outer wall of the section is bulged outwardly next to this opening to admit of a' larger opening without unnecessarily increasing the size of the section. Equidistant from the center on the opposite side the outer wall is bulged outwardly in like manner, so that another outlet-opening from the water-space b may be made when the heater is to berused for generatingsteam.

The heater, as shown in the drawings, is specially designed for hot-water heating; but by a few simple changes, which will be hereinafter explained,it may be readily adapted for steam-heating.

D is a section fitted at the bottom to and mounted upon the re-pot section B. It may be for convenience of description designated the feed-door section. It is formed With two segmental or horizontally-curved ueopenings d, extending upwardly through it and dividing the Water-space into an outer channel or passage CZ and an inner passage d2. It is also formed in the front side with a feed-door opening cl3 and at the top, on opposite sides of said door-opening, with inlet and outlet openings d* and d5, respectively. The outer wall of thevsection is bulged or curved outwardly next to the inlet and outlet openings to correspond with the bulges on the firepot section, and when the heater is to be used for steam-heating an extra inlet-opening may be made in the bottom below the outlet-opening d5. The outer water channel or passage d' communicates at one end with the inlet-opening di and at the opposite end with one end of the inner passage or channel d2, the other end of the inner channel being eX- panded horizontally and rearwardly over the central portion of the fire-pot and communicating with the outlet-opening d5, which when the heater is used for hot-water heating is separated from direct communication with the outer passage d by a partition d6; but when the heater is used for steam-heating this partition is preferably omitted. The outer passage d corresponds in width with the waterspace b in the fire-pot section and extends from top to bottom of the feed-door section. The inner passage d2 at the back is made of less depth and opposite the feed-door opening is recessed or cut away on the under side to afford a clear space for the supply of fuel to the lire-pot and at the same time to bring an extended area of water-heating surfaces in said feed-door section directly over and close to the re.

E is a section which may be called the crown-section, fitted at the bottom and mounted upon the top of the feed-door section and formed with a segmental or horizontally-curved {lue-opening e, which when the sections of the heater are assembled is above and opposite the curved water-passage d2 of the lire-pot section, so that the lire and heated products of combustion passing upwardly through the flue-openings in the feed-door section will impinge against and be deflected by heatfabsorbin g and water-heatingsurfaces of said crown-section, which is recessed on the under side, as shown in Fig. l, to aiford free communication between the flue-openings CZ d in the feed-door section and the flue-opening e in the crown-section.

' formed in' the bottom with an inlet-opening c', which registers with the outlet-opening (Z5 inv the section below it and is bulged out-l wardly around said opening to correspond with the bulge on section D. The flue-opening e divides the water-space of section E `into an outer circular passage e2 and an inner circular chamber e3, which has a central outlet-` opening'e4 in the top. The passage ez communicates at one end with the inlet-opening e'and at the opposite end with the chamber; c3, direct communication between the inlet e in the bottom with a central inlet-opening f` and is connected with and supported a short distance above section E by a nipple or short i pipe-sectionf, which is inserted in the ex-` ternally-'flanged openings c4 andf of said seci tions. The section F is formed at the rear on top with an externally-flanged outletopeningj'2, with which the service-pipe G is connected. Between the inlet and outlet openings fand f2 this section is formed with a semicircularV baffle-plate or deiiecting-partition f3, which is open on the front side.

H is a smoke-box which incloses a space around the top section F. It is formed on top with a'central flanged opening h, with which the smoke-pipe I is connected. The section F is 'preferably made somewhat smaller in diameter than the section E, so as to allow a passage for the smoke and products of combustion all around it without extending the smoke-box H much, if any, beyond the'outer walls of the heater-sections below it.

The registering openings in the sections B, D, and E are preferably provided with plain 4slip-nipples J to allow for unequal expansion and contraction of the parts and to avoid leakage; but other coupling devices, such as screw-threaded nipples or pipe-sections, may `be used.

The lire-pot B of my heater, as herein shown and described, does not have a feeddoor, with which the corresponding sections of heaters of this class are usually provided; but the feed-door opening is made in the sec- The crown-section is 4 tion above it. In this way a deep fire-pot is afforded and provision is made for a comparatively large body of fuel,by which economy and efciency in the operation of the heater are secured. It will also be observed that the feed-door section of the heater has a large area of heat-absorbing and water-heating surface directly over and in close proximity with the fire and directly exposed to the heated products of combustion as they escape through the flue-openings in said section and that the water in its passage from the inlet to the outlet of the heater has to travel a long distance, as indicated by the arrows on Fig. 2, in contact'with highly-heated surfaces. to travel in a sinuous course to reach the exitvflue I and in so ldoing part with all their available heat to the heat-'absorbing and water-containing walls with which they come in contact.

The flue-spaces between the sections D, E, and F and above the section F are reached and cleaned out by doors K, L, and M. (Shown in Fig. l.)

For steam heating in addition to the changes hereinbefore noted the top orca'p section F is made deeper and provided with a water-gage, so as to afford means for maintaining a steam-space above the water-level in said section. H is correspondinglyincreased, and the partition or baffle-plate famay be omitted. In other respects the heater may be made for this purpose as shown in the drawings.

The depth of the smoke-box p The products of combustion have also IOO As constructed for hot-water heating the cool feed-Water entering through pipe C-passes in both directions through the annular water-space?) to the outlet-opening b2 in section B, in which it is partially heated. From this section it passes through the outlet-opening b2 into the section D, in which it passes vback and forth in a circuitous path through the passages d and d2 to the outlet-opening d5, whence it escapes into section E, traversing the circular passage e2 of this section and escaping therefrom through its outlet-opening e4 into the top section F. From the inletropening in this section it iiows in both directions around the ends of the partition or baffle-plate f3 through the outlet-opening f2 into the service-pi pe G. As constructed for steamheating the circulation is substantially the same, except that the water and the steam liberated therefrom in section D may'iow di'- rectly from both the passages d and d2 through the outlet-opening d5 into the section E next above it, and the water is not allowed torrise above a certain level in the top section F.

Various modifications in the details'of construction may be made without material effect upon the operation of the heater and without departing from the spirit and intended scope of my invention. For instance, the number and arrangement of the sections may be varied. The'top section F may be omitted in some cases, the service or llowv IIO pipe Gr being connected directly with the outlet e4'of section E and the smoke-box I-I and the location of the smoke-flue connection h being modified accordingly in such cases, or the heater may have one or more additional sections like or similar to and mounted upon section D, each additional section having no dooropening, but a water space or passage extending entirely around it.
